WIRE-ROPE CHOKEBr-SLING.

To allwhom it may concern: v

Be it known that we, JOHN A. Buonpnr and, JOSEPH NADEAU, citizens of the United States, residing at Port Alberni, 1n the Province of British Columbia, Canada, have invented certain new and useful improvements in Wire-Rope Choker-Slings, of which the following is a specification.

This invention relates to a means for connecting one end of a wire rope to the intermediate portion to form such as is used in logging operations for connecting the logs to the tag line.

The invention is particularly described in the following specification, reference being made to the drawings by which it is accompanied', in which:

Figure 1 shows the device in its simplest form. I

Fig. 2 shows the application of it to a log as a choker or sling.

Fig. 3 shows an improved form of the device. I

Fig. 4 is a vertical section of the same and- Fig. 5 shows its application on a log. In these drawings 2*represents the wire rope of thesling which has a thimbled enlargement 3 and 4 at each end. It is required'toconnect either end 3 or 4 of this sling to the intermediate portion 2' in a manner .that the sling will tighten on the log with the tension of the haul .and be readily connected to and released there-from.

Fig. 1 shows this connecting device in its simplest form. It comprises a relatively broad piece of metal 5, one end 7 of WlllCh is formed as an eye in which the wire rope 2 of the sling is freely movable 'endwise, and the other end is bent around as at 6 to form a hook. The middle portion of the hook end 6 is notched as at 8 to receiye the wire rope of the sling and retain It In the hook enlargement 3 or 4 of its end.

- The wire rope of the sling 2 is threaded- 4'5 through the eye 7 before one ofthe thimble enlargements is secured on it, so that the member 5 is relatively permanently connected on the sling 2 and is free to move on it from end to end.

. In use, the sling2 is passed around a log A and onethimbled end 3 is passed into the notch 8 of the hook 6 while the other end 4 of the sling is connected by any su ta le Specification of Letters Patent.

- means to the tag line, preferably by means ,of a simllar keyhole apertured fastening 12,

such as is illustrated;

Or, as shown in Fig. 2, the member 5 is moved along the rope sling 2 until the end 4 s stopped against the eye 7 and the sling belng passed around the log and the end 3 connected to the tag line, the bight of the sling 2 is passed overthe hook 6, whereby the sling has a self-tightening hold on the Although the device as described possesses the principal elements of the invention, the notch 8 does not afford the end of the sling a secure hold when used over rough or uneven country. It is to avoid accidental release at this point that the modification illustrated in Fig. 3 has been designed. In this construction, while the hook 6 is substantially as in Fig. 1, instead of providing the notch 8 in the front or point side of the.

hook, the member 5 has an elongated slot 10, adapted to pass the wire rope carried vertically from adjacent the eye 7 to the bend of the hook 6, as shown in Fig. 4.

This slot 10 has an enlargement 11 at its upper end through which the thimbled enlargement 3 or 40f the rope sling 2 may be passed, Either end 3 or 4 of the sling 2 may be passed through the enlargement 11 and moved down the slot 10 to the bend 6 of the member 5 and thus form a connection between either end and the intermediate portion of the sling that will not readily release and that yet may be easily-connected or disconnected at will. The change in this detail of construction does not in any way deviate from the general principle of the hook as set forth in Fig. 1.

The device, particularly that set forth in Figs. 3 and 4, forms an eminently simple, convenient, and secure means for connecting eitherend to the intermediate portion of a sling, in a manner that the pull on the rope will tighten the hold of the sling on a log.

For ordinary straight ahead work the device is applied as in Fig. 2, when the hook 6 of the connecting means may be ra idly connected to the bight of the interme diate portion 2; whereas, if the work is being conducted through and over rough country, where the sling end might become disengaged from the hook 6, the connection is apend of the sling through plied, as shown in Fig. 5, by passing one the enlarged aperture 11 and down the slot 10 to the bend of the hook, ling connection cannot become disengaged in use.

aving now particularly described our invention we hereby declare that what we claim as new and desire to be protected in by Letters, Patent, is:

l. A means for connecting the end of a wire rope to the intermediate portion thereof to form a choker or sling, said means com.- prising the combination with a length of Wire rope having a retainer enlargement at one end, of a member endwise movable freely on the rope, for removable connection largement of the rope end.

A means for connecting wire rope to the intermediate portion thereof to form a choker or sling, said means comprising the combination with a length of wire rope having an enlargement at one end means for connecting the end of a wire rope to the intermediate portion thereof form a choker or sling, said means comprising the combination with a len wire rope having an enlargement at one end, of a member freely movable endwise on the rope, said member being of relatively greater breadth than thickness and having a hook bend of which is substantialy parallel to t e eye which is movable on the rope, and means in the mid-width) of the hook for ment at the end the end of a receiving the rope and retaining theenlargethereof.

means for connecting the end of a wire rope to the intermediate portion thereof to form a choker or sling, said means comprising the combination with a length of Wire rope having an enlargement at one end, a member having an eye atone end through of, and the end adjacent the eye isenlarged to receive the enlargement.

5. A means for connecting the end of a wire rope to the lntermediate portion thereof to form a choker or sling, said means comprising the combination with a length of wire rope having an enlargement at one end, a member having an eye at one end through which the wire rope may freely pass and at the other end is outwardly turned parallel to the eye, said member having a keyhole aperture the enlargement of which is adjacent to receive the enlargeand extends therefrom to the outwardly turned end where it is adapted to permit passage of the rope but will retain the enlargement at the end thereof.

In testimony whereof we aifix our signatures.
